Lights out for this light weight

Tomorrow morning I'm expected to hand in a digitized self-portrait in order to prove my knowledge of the electronic submission process. I probably didn't have to do this much work (which really isn't much as I'm reusing a drawing I'd done months ago) but I liked this concept and decided to run with it.

If you're wondering how I accomplished this I've included the unedited drawing, the final image, and this snazzy .gif. Basically all I did was take a photo and plop my drawing on top of it, playing around with levels, exaggerating hues, and making the computer the sole light source.
